[0003] Fluid drives include fluid drives and liquid drives. Liquid drives mainly use various fluid pumps and propellers. Fluid drives also include fans, blowers, pumps, compressors, and more.

[0004] Most fluid pumps use an impeller structure, which is prone to forming strong vortex disturbances and is destructive to mixed materials containing solid blocks in the liquid. It is also easy to generate strong noise due to the vortex.

[0005] For propellers with a large flow rate of driving liquid, it is also easy for the propeller surface to be corroded by the "cavitation effect", and it is easy to produce strong noise.

[0041] In order to make the technical means, creative features, objectives and effects of the invention easier to understand, the invention is further explained below with reference to specific illustrations.

[0042] 1 to 11 , the circulating fluid power system includes a circulating pipe 3; the circulating pipe 3 is provided with a fluid inlet 5 and a fluid outlet 6; an openable valve 4 is provided between the fluid inlet 5 and the fluid outlet 6; when the valve 4 is closed, it blocks the fluid from the fluid outlet 6 from flowing to the fluid inlet 5, thereby controlling the flow of fluid; and further includes a driving device a disposed within the circulating pipe 3 and circulated along the circulating pipe 3;

[0043] The interior of the circulation pipe 3 adopts a channel with a circular ring structure;

[0044] The driving device a is at least partially structured in the length direction to have an arc that fits the inner wall of the circulation pipe 3;

[0045] An energy input device is provided to provide energy for the movement of the driving device a; the energy input device is an energy input device that inputs at least one of electricity and magnetic force; the driving device a has a structure for pushing the fluid to flow in the circulation pipe 3; the shape of the opening of the valve 4 in the conductive state is a shape that allows the driving device a to pass through;

[0046] The driving device a includes a device bracket;

[0047] The device bracket is provided with a fluid pushing mechanism a4 that allows pushing the fluid in the curved circulation pipe 3. The fluid pushing mechanism a4 is provided with a fluid blocking structure for pushing the fluid.

[0048] At least two rolling components supporting the fluid pushing mechanism a4 are also provided on the device bracket. The rolling components are at least one of balls, rollers, and rollers. The rolling components are pressed against the inside of the circulation pipe to support the device bracket and the fluid pushing mechanism a4.

[0049] The valve 4 adopts a shaft rotation structure.

[0050] The circulation pipe 3 has a channel with a circular ring structure inside, so that the driving device a can circulate through the circulation pipe 3.

[0051] Through the above design, the driving device a can be used to push the fluid in the circulation pipe 3 to move from the fluid inlet 5 to the fluid outlet 6 and be discharged from the fluid outlet 6.

[0052] The circulation pipe 3 adopts a circular ring structure with a radius of 0.3 meters to 2 meters.

[0053] The circulation radius of the circulation movement in the circulation pipe 3 is limited to an adaptable range of 0.3 meters to 2 meters. This value is an optimal value verified by the inventor to ensure efficiency, ease of construction, and convenience of transportation, and to balance and integrate multiple advantages.

[0054] The driving device a includes a device bracket.

[0055] The device bracket presents an arc-shaped structure in the front-to-back direction.

[0056] To match the circular movement of the ring.

[0057] The device bracket presents an arc-shaped structure with a radius of 0.3 meters to 2 meters in the front-to-back direction.

[0058] The adaptability range of the circulation radius of the circulation movement is limited to 0.3 meters to 2 meters. This value has been verified by the inventor to be an optimal value that ensures efficiency, ease of construction, and convenience of transportation, and balances and integrates multiple advantages.

[0059] The driving device a is configured to allow the valve 4 to pass through, so that the driving device a is allowed to perform cyclic movement, allowing the fluid to be squeezed continuously, and the squeezed fluid is discharged from the fluid outlet 6.

[0060] The energy input device may be a structure connected to an external power supply system, and the motor a1 is provided in the driving device a to obtain moving energy through electricity.

[0061] The energy input device can also be a structure connected to an external moving magnetic system, and the driving device a is provided with a linked magnetic structure to obtain moving energy through magnetic force.

[0062] Compared with the conventional piston compressor structure, the above design has a higher energy conversion rate because there is no need to waste energy by decelerating or reversing the piston.

[0063] Furthermore, since no reverse movement is required for reset, larger equipment can be built. Systems with fluid capacity thousands, or even tens of thousands, of times larger than piston cylinders can be manufactured at a relatively low cost. Furthermore, higher power can be achieved while the drive unit moves at a lower speed.

[0064] Because the movement speed of the driving device a is allowed to be lower, the precision of the structural structure is lower than that of the piston, which is more conducive to production, has lower production costs, and is more stable and reliable in operation.

[0065] Compared with the idea of ​​reducing the weight of the piston as much as possible in order to reduce the energy consumed during the direction change process in piston design, this patent allows the drive device a to have a higher mass (weight) and allows for a more complex structural setting, thereby improving performance.

[0066] In addition, since there is no problem of changing the direction of the piston's movement, problems such as noise and wear are smaller.

[0067] In comparison, whether it is a traditional piston structure, propeller structure, turbine structure, or scroll structure, they all produce much smaller vortices.

[0068] For solid blocks within the fluid, the destructiveness is greatly reduced, and therefore the noise is greatly reduced.

[0069] For example, when driven by fluid (gas or liquid) containing solid blocks such as bacteria, fish eggs, fish fry, aerogels, etc., the damage to the solid blocks can be greatly reduced, thus playing a better protective role.

[0070] For designs with large driving liquid flow, since this patent does not have a propeller, there will be no "cavitation effect" on the propeller surface, thus avoiding equipment corrosion and noise.

[0071] When used on board ships, especially on submarines, it can effectively improve the quietness effect.

[0072] An energy input device is also provided to input the energy for driving the driving device a into the circulation pipe 3.

[0073] Because the drive device a is supported by the inner wall of the circulation pipe 3, it can withstand much greater centrifugal force and airflow disturbance than the propeller, allowing it to have a higher speed and output greater power.

[0074] At the fluid outlet 6 , a fluid valve is provided to limit the backflow of the fluid outside the fluid outlet 6 to the circulation pipe 3 .

[0075] When the driving device a has just moved past the fluid outlet 6, or when the valve 4 is opened, causing the fluid inlet 5 and the fluid outlet 6 to be connected, the fluid valve restricts the high-pressure fluid connected to the fluid outlet 6 from flowing back into the circulation pipe 3, or even to the fluid inlet 5.

[0076] This design is suitable for environments where the pressure outside the fluid outlet 6 is greater than the pressure outside the fluid inlet 5, such as a compressor.

[0077] The pressure outside the fluid inlet 5 (air inlet) of the compressor (such as a normal pressure environment) is greater than the pressure outside the fluid outlet 6 (air outlet) (such as a gas storage tank).

[0078] The provision of a fluid valve can prevent fluid backflow and achieve efficient pressurization outside the fluid outlet 6 (air outlet).

[0079] In an environment where the pressure outside the fluid outlet 6 and the fluid inlet 5 is similar, a fluid valve may not be provided. For example, a fan or a liquid pump.

[0080] The circulation pipeline can be a curved pipeline. During operation, at least two rolling components abut the inner wall of the curved pipeline, supporting the drive device and fluid propulsion mechanism a4, converting at least a portion of the sliding friction on at least one side of the fluid propulsion mechanism a4 into rolling friction. When the rolling components are balls, top ball bearings can be used.

[0081] The sliding friction is converted into rolling friction by the rolling components, thereby allowing the fluid propulsion mechanism a4 to operate at a much higher speed.

[0082] Even when running at higher speeds, there will be little wear on the contact parts. Mechanically, it has better reliability and a much longer service life.

[0083] In summary, the operating speed and efficiency of the equipment can be improved, the failure rate of the equipment can be reduced, and the service life of the equipment can be greatly extended.

[0084] The fluid propulsion mechanism a4 in the present invention is essentially different from the traditional piston.

[0085] Traditional piston pump pistons or cylinder pistons are required to withstand strong instantaneous high pressure, so they adopt technical designs that can withstand high pressure, have strong sealing properties, and not move at too high a speed.

[0086] The average operating speed of a traditional piston pump piston or cylinder piston is generally less than 3 meters per second.

[0087] The provision of rolling elements on conventional piston pump pistons or cylinder pistons cannot reduce the friction of the "annular sealing strip" with high sealing strength. Therefore, conventional pistons are not suitable for the design of the present invention.

[0088] The design of this invention is not intended to withstand instantaneous high pressures, but rather to accommodate operating environments requiring minimal sealing, minimal pressure differentials, and sustained high speeds. The design of this invention is designed to allow for speeds exceeding 10 meters per second, and even exceeding 40 meters per second. This is fundamentally different from traditional piston designs.

[0089] This technical requirement was encountered by the inventor of the present invention while carrying out other original designs.

[0090] In the present invention, by allowing for reduced sealing and lowering the pressure differential, the friction of the sealing mechanism (the fluid-blocking structure that pushes the fluid) is low. By supporting the fluid-pushing mechanism A4 with rolling elements, friction can be further reduced. By reducing sliding friction, the technical advantage of sustained high-speed operation is achieved.

[0091] In summary, the inventors of the present invention not only creatively opened up a technical demand, but also overcame the prejudice of the existing technology and designed a fluid propulsion mechanism a4 that reduces sealing and pressure difference, but has the outstanding technical advantage of continuous high-speed operation.

[0092] Many of the following designs are designed to adapt to continuous high-speed unidirectional operation, a technical requirement that previous piston technology has never encountered.

[0093] Valve 4 uses a rotating shaft structure, rather than the more commonly used push-pull structure with better sealing performance. By giving up some of the sealing advantages, the valve can better withstand impact from the drive device, protecting equipment safety. Even if the valve is opened too slowly and is impacted by the drive device, it will use the momentum to reverse and release the force.

[0094] In addition, the shaft rotation structure can have a shorter height or length extension of the valve system located outside the circulation pipeline than the push-pull structure.

[0095] The valve 4 adopts a rotating shaft structure, and the rotating shaft is sealed in the cavity accommodating the valve, and the cavity is airtightly connected to the circulation pipe 3; thereby, the rotating shaft is sealed in the space connected to the circulation pipe 3.

[0096] The valve 4 adopts a rotating shaft structure, and the rotating shaft is sealed in the cavity of the door plate accommodating the valve, and the cavity is airtightly connected to the circulation pipe 3; thus, the rotating shaft is sealed in the space connected to the circulation pipe;

[0097] The cavity accommodating the valve is provided with a recess such as the arc-surface recess C4 on the side opposite to the rotating shaft; when the edge of the door panel rotates downward, it is close to the arc-surface recess such as the arc-surface recess C4.

[0098] Although the sealing performance between the fluid inlet and outlet is somewhat weakened, it can be easily designed into the structure shown in Figure 10, making the circulation pipe 3 easily sealed from the outside world, thereby preventing fluid leakage, especially the leakage of toxic and hazardous substances. The expensive and fragile shaft seals used in traditional valves are eliminated. Furthermore, the sealing performance is improved through structures such as the arc-shaped recess C4.

[0099] The fluid valve b can be a one-way valve.

[0100] A control circuit may be provided, and a signal acquisition interface of the control circuit may be connected to a sensor for detecting the operating status of the propulsion device;

[0101] The control signal output interface of the control circuit controls the connection energy input device.

[0102] By detecting the propulsion device, feedback control is performed on the energy input device to ensure that the propulsion device operates stably in an appropriate state. The sensor for detecting the operating status of the propulsion device can be a speed sensor.

[0103] A pressure sensor for detecting the pressure in the circulation pipe 3 is also provided, and the signal acquisition interface of the control circuit is connected to the pressure sensor.

[0104] The moving speed of the pushing device may be reduced after the fluid pressure in the circulation pipe 3 reaches a set index.

[0105] A flow sensor for measuring the amount of fluid flowing into the fluid inlet 5 is also provided, and the control circuit is connected to the flow sensor.

[0106] To achieve composite detection and facilitate the formulation of composite solutions.

[0107] The structure for pushing the fluid on the driving device a, namely the fluid pushing mechanism a4, includes a sheet-shaped baffle.

[0108] A flexible sealing structure a5 is provided around the baffle.

[0109] The flexible sealing structure a5 is against the inner wall of the circulation pipe 3. The flexible sealing structure a5 can be a sealing strip or a flexible sheet. Preferably, it is a flexible rubber sheet. The baffle is preferably a metal plate.

[0110] Specifically, preferably, the structure for pushing the fluid on the driving device a adopts a metal plate, and the metal plate is provided with a flexible rubber with outward tension extending beyond the edge of the metal plate.

[0111] The flexible rubber is pressed against the inner wall of the circulation pipe 3 to ensure air tightness.

[0112] The flexible rubber can be in the form of a sealing strip, a sealing ring or a rubber sheet.

[0113] Compared with sealing strips, rubber sheets are easier to set to a longer width and have more redundancy after wear.

[0114] Metal plates have the advantages of strong pressure resistance and not easy to age.

[0115] The structure for pushing the fluid on the driving device a may be the structure of the driving device a itself.

[0116] The driving device a may also have an arc-shaped tubular structure; at least a portion of the outer side of the arc-shaped tubular structure is attached to the inner wall of the circulation pipe 3; the structure of the driving device a itself serves as the structure for propelling the fluid.

[0117] Because of its tubular shape and length, it is easy to form a seal in the longitudinal direction. Even if the fit is not very tight, the viscosity of the fluid will form a strong seal.

[0118] It can ensure that the connection with the inner wall of the circulation pipe 3 is not very tight, or even there are gaps, and the friction is small, while having good sealing performance and improving efficiency and performance.

[0119] The length of the arc-shaped tubular structure attached to the inner wall of the circulation pipe 3 is not less than 5 cm.

[0120] The arc-shaped tubular structure is provided with at least one annular recess, and an annular sealing strip is installed in the annular recess.

[0121] A seal is formed by an annular sealing strip.

[0122] The circulation pipe 3 is preferably provided as a horizontal circulation pipe 3 .

[0123] Laying flat does not mean being absolutely horizontal. It is limited to an angle of less than 30 degrees with the horizontal plane. This allows the drive device a to move on a relatively flat plane.

[0124] Reduce design difficulty and improve system stability during movement.

[0125] An opening is provided above the circulation pipe 3 and is sealed by a detachable cover.

[0126] An opening is allowed to be provided above the circulation pipe 3, which can reduce the difficulty of production and facilitate future maintenance.

[0127] A control circuit can be provided, and a signal acquisition interface of the control circuit is connected to a sensor for detecting the operating status of the driving device a; a control signal output interface of the control circuit is connected to control the power input to the driving device a.

[0128] By detecting the driving device a, feedback control is performed on the power input driving device a, so that the driving device a can operate stably in a suitable state. The sensor for detecting the operating status of the driving device a can be a speed sensor.

[0129] A pressure sensor for detecting the pressure in the circulation pipe 3 is also provided, and the signal acquisition interface of the control circuit is connected to the pressure sensor.

[0130] The movement speed of the driving device a may be reduced after the fluid pressure in the circulation pipe 3 reaches a set index.

[0131] A flow sensor for measuring the amount of fluid flowing into the fluid inlet 5 is also provided, and the control circuit is connected to the flow sensor.

[0132] To achieve composite detection and facilitate the formulation of composite solutions.

[0133] The valve 4 can be a shaft rotating structure or a push-pull structure. For example, a revolving door structure can be used.

[0134] Referring to Figure 8, preferably, the valve 4 adopts a revolving door structure; the revolving door includes a rotating shaft C1, and at least two door panels C2 rotating around the rotating shaft C1; the circulation pipe 3 is provided with a revolving door cavity C3 cooperating with the revolving door at the valve 4; the edge of the door panel C2 rotates in contact with the inner wall of the revolving door cavity C3; the revolving door cavity C3 is provided with two ports, one port facing the fluid inlet 5, and the other port facing the fluid outlet 6; the revolving door has a posture of allowing the driving device a to pass through, and a posture of blocking the fluid between the fluid inlet 5 and the fluid outlet 6.

[0135] The on-off is controlled by a rotating structure, which runs more smoothly than a telescopic or flap structure.

[0136] Assume that the following description uses the perspectives of Figure 8 when the circulation duct 3 is horizontal, and Figures 9 and 10 when the circulation duct 3 is vertical. The rotating door cavity C3 of the circulation duct 3 comprises an upper and lower portion. The upper portion comprises a cavity portion that protrudes above the inner wall of the circulation duct, and the rotation axis C1 is disposed in the upper portion.

[0137] The upper cavity portion is provided with a curved surface, and when the edge of a door panel C2 is rotated upward, it fits into the curved surface;

[0138] The lower part includes a portion lower than the inner wall of the circulation pipe, and a curved recess C4 is provided on the lower part. When the edge of a door panel C2 rotates downward, it is close to the curved recess C4.

[0139] By arranging the rotating shaft at the upper part, the rotating shaft is prevented from obstructing the driving device a.

[0140] By providing the upper curved surface and the lower curved surface depression C4, the edge of the door panel C2 has a higher fit and better sealing performance.

[0141] Furthermore, the curved surface and the curved recess C4 have a similar curvature, and a sliding plate C5 with a similar curvature is provided on the edge of the door panel C2.

[0142] The so-called sameness allows for a reasonable range of errors.

[0143] By providing the sliding piece C5, the width of the joint between the door panel C2, the curved surface and the curved surface recess C4 is increased, and the viscosity of the fluid is utilized to improve the sealing performance.

[0144] It does not increase the rotational friction, reduces energy consumption, prolongs the service life, and improves the sealing and efficiency.

[0145] The width of the sliding piece C5 is preferably greater than 1 cm.

[0146] The width is calculated along the direction of fluid flow.

[0147] Different from FIG8 , FIG10 adopts a structure in which the valve 4 is placed horizontally.

[0148] Specific implementation 1 (electrical energy introduction system using conductors)

[0149] The energy input device includes an electric energy introduction system;

[0150] The electric energy introduction system includes an electric system arranged on the driving device a, and a conductive mechanism for inputting electric energy through the circulation pipe 3;

[0151] The electric system on the driving device a includes an electric motor a1 and a rolling device a3 linked to the rotor of the electric motor a1. The rolling device a3 directly or indirectly abuts against the inner wall of the circulation pipe 3.

[0152] The power input terminal of the motor a1 is connected to the conductive mechanism.

[0153] The rolling device a3 can be the rolling component mentioned above, or can be two different components.

[0154] Preferably, the rolling device a3 and the rolling component are the same component, thereby simplifying the structure and reducing the failure rate.

[0155] The specific usage is:

[0156] Electric energy is input into the circulation pipe 3 through the conductive mechanism and supplied to the motor a1. The rotor of the motor a1 is linked with the rolling device a3, which in turn causes the rolling device a3 to roll and drives the driving device a to move.

[0157] The above design is creative in that the motor a1 is built into the circulation pipe 3 for fluid circulation, and the motor a1 moves along with the driving device a. Air is compressed in the dynamic state.

[0158] In traditional designs, the motor is fixed and other power components are used to drive the working parts of the compressor. However, the patent of this invention uses the design of using motor a1 to move along with the power component (drive device a), which is a completely different design concept.

[0159] In traditional designs, those skilled in the art would believe that the more stable the motor installation is, the better, as it is more conducive to stable operation, easier power input, easier maintenance, and less likely to waste energy.

[0160] The above design of this patent overcomes the above technical prejudice, moves the motor A1, and achieves unexpected technical effects.

[0161] This system has the following advantages: It effectively utilizes the space within the circulation pipe 3, reduces external space occupation, and facilitates the external layout of auxiliary structures. Furthermore, by adding the weight of the motor a1 to the drive device a, the inertia is increased, effectively resisting sudden fluid pressure fluctuations and ensuring smooth and stable operation.

[0162] It should be noted that "passing" does not mean entering, but may mean passing through or crossing. The valve 4 may be opened before the driving device a passes through the fluid outlet 6 or after the driving device a passes through the fluid outlet 6.

[0163] (1) Power input

[0164] 7 , the power introduction system includes an electric system provided on the drive device a, and the power input port of the motor a1 in the electric system is connected to at least two contacts;

[0165] A conductive mechanism is provided in the circulation pipe 3;

[0166] The power input port is movably connected to the conductive mechanism through at least two contacts.

[0167] Ensure that current can be input from the conductive mechanism during the movement of the electric system.

[0168] Furthermore, preferably, the conductive mechanism is a strip conductor a6 provided on the inner wall of the circulation pipe 3 .

[0169] The strip conductor a6 can be connected to the outside through one of the openings of the fluid inlet 5 and the fluid outlet 6 to input electrical energy from the outside.

[0170] Avoid connecting to the outside world through additional openings.

[0171] The strip conductor a6 may be a copper conductor bar disposed in the circulation pipe 3 .

[0172] The power input port of the motor a1 is conductively connected to at least two contacts;

[0173] The inner wall of the circulation pipe 3 is provided with at least two strip conductors a6 of a conductive mechanism;

[0174] At least two contacts respectively press at least two strip conductors a6 to achieve conduction.

[0175] In the above design, the contact and the strip conductor a6 are pressed together by gravity, which has the characteristics of high stability and simple structure.

[0176] At least one slide plate structure is provided below the driving device a, and the slide plate structure is in contact with the bottom of the circulation pipe 3 for at least 5 cm in the front-to-back direction.

[0177] When the driving device a passes through the valve 4, the slide structure can effectively reduce vibration, make the operation smooth, and effectively protect the motor a1.

[0178] The contact can be set on the slide structure, with the contact point being below the slide mechanism, to simplify the structure, reduce costs and improve stability.

[0179] More preferably:

[0180] At least two contacts, which can be rolling contacts, can reduce friction and avoid wear.

[0181] The rolling contact may be at least one of a roller, a ball, a roller, and a wheel with teeth.

[0182] (2) Rolling device

[0183] The rolling device a3, which is linked to the rotor of the motor a1, is formed of at least one of a roller and a gear.

[0184] A track with resistance is provided on the inner wall of the circulation pipe 3, and the rolling device a3 rests on the track.

[0185] By increasing the resistance, the rolling device a3 generates more force and displacement, thereby completing more energy conversion.

[0186] Specifically, preferably, the rolling device a3 is a gear, and a rack meshing with the gear is provided on the inner wall of the circulation pipe 3. The rack serves as a track.

[0187] The meshing structure of the gears can withstand and output greater forces and has the characteristics of high energy output.

[0188] The rack is arranged on the side wall inside the circulation pipe 3.

[0189] The arc-shaped structure of the circulation pipe 3 has a side close to the center of the circulation pipe 3 and a side away from the center of the circulation pipe 3, both of which are side walls.

[0190] It is arranged on the side wall to avoid the problem of different radii and tooth spacing on both sides of the rack due to the arc structure of the circulation pipe 3. It also avoids the complexity of the gear needing to adopt a bevel gear.

[0191] Use the track as the conductive mechanism. Combine the two into one.

[0192] The contacts are conductive rollers with conductive outer sides.

[0193] Preferably, the rolling device a3, the rolling component, and the conductive roller are the same component, thereby simplifying the structure and reducing the failure rate.

[0194] The contact adopts a conductive roller with conductive outer side, and the outer side of the conductive roller has a tooth structure;

[0195] The teeth of the conductive roller and the strip conductor a6 are meshed, and the tooth structure and the tooth-bar structure cooperate in such a manner that at least four teeth on the conductive roller are in contact with the strip conductor a6 at the same time.

[0196] At least four teeth on the conductive roller are in a conductive state, which further ensures lower resistance and more stable electrical connection.

[0197] The rolling device a3 is provided with a roller, and the roller is a conductive roller.

[0198] The rolling device a3 and the conductive roller are combined into one, so that the conductive roller has both the conductive function and the rolling support function.

[0199] (3) a rolling device a3 linked to the rotor of the motor a1, using a roller (including a gear-type roller);

[0200] A track with resistance is provided on the outer inner wall of the circulation pipe 3, and the rolling device a3 rests on the track;

[0201] By increasing the resistance, the rolling device a3 generates more force and displacement, thereby completing more energy conversion;

[0202] Specifically, preferably, the rolling device a3 uses a roller with a toothed structure, and a rack meshing with the toothed structure is provided on the outer inner wall of the circulation pipe 3, with the rack serving as a track.

[0203] The meshing structure of the gears can withstand and output greater forces and has the characteristics of high energy output.

[0204] The rack is arranged on the outer inner wall (outer ring) of the circulation pipe 3 .

[0205] It is arranged on the outer wall to avoid the problem of different radii and tooth spacing on both sides of the rack due to the arc structure of the circulation pipe 3. It also avoids the complexity of the gear needing to adopt a bevel gear.

[0206] In addition, considering the effect of centrifugal force, when the fluid drive device A performs circular motion, centrifugal force is generated, pressing the outer and inner walls. The roller can provide a good "grip" to prevent slipping, and can also support, position and protect the fluid drive device A.

[0207] (4) Driving device

[0208] The motor a1 is connected to the rolling device a3 through a speed change system a2 so as to make the force smooth and reasonable.

[0209] The speed change system a2 adopts a speed change system a2 with an adjustable speed ratio.

[0210] When the speed of the motor a1 is set to exceed the speed of the rolling device a3, that is, when the speed is increased, the speed ratio is increased during startup, the speed of the rolling device a3 is reduced, and the thrust required for startup is reduced.

[0211] This is to reduce the thrust required for starting, make starting smoother, and protect internal stress-bearing components.

[0212] After starting, when the speed of the driving device a exceeds the set value, the speed ratio is reduced, the speed of the rolling device a3 is increased, and the speed of the motor a1 is allowed to increase.

[0213] A control circuit can be set up, and the control circuit is connected to a sensor (which can be an optical sensor, a Hall sensor, etc.) for detecting the running speed of the drive device a. When the sensor detects that the drive device a is lower than a set speed, the control circuit reduces the speed ratio; when the sensor detects that the drive device a is higher than a set speed, the control circuit increases the speed ratio.

[0214] In order to automatically adjust the power output efficiency and the operating speed of the drive device in a timely manner, make the operation smooth, protect the internal stress-bearing components, and improve the driving efficiency.

[0215] Specific implementation 2 (energy input device using external magnet mechanism)

[0216] Another design of the energy input device is as follows.

[0217] The energy input device inputs energy into the circulation pipe 3 through magnetic force, and is provided with a power input drive device a for inputting power from the outside.

[0218] The driving device a includes a magnet mechanism, which is called the internal magnet mechanism 1;

[0219] The internal magnet mechanism 1 includes at least one of a permanent magnet and a soft magnet;

[0220] A power input drive device a is also provided for inputting power from the outside;

[0221] The power input drive device a is provided with a magnet mechanism linked to the internal magnet mechanism 1 through magnetic force, which is called the external magnet mechanism 2.

[0222] When the internal magnet mechanism 1 is located in front of the fluid inlet 5 and between the fluid inlet 5 and the fluid outlet 6 , the driving device a is in a state of pushing the fluid entering the fluid inlet 5 to flow toward the fluid outlet 6 .

[0223] During use, fluid is introduced into the fluid inlet 5, and the circulation pipe 3 is a channel for the fluid to circulate;

[0224] Driven by the driving device a, the fluid moves along the circulation pipe 3 toward the fluid outlet 6;

[0225] During the movement of the driving device a, the valve 4 is kept open by triggering the mechanical mechanism or the motor 8. When the driving device a reaches the valve 4, the valve 4 is kept open.

[0226] The driving device a passes through the valve 4 and the fluid inlet 5, and then pushes the fluid to move again, forming a cyclic movement process;

[0227] In the process of driving device a pushing the fluid to move, external energy drives the power input into driving device a to work, so that the external magnet mechanism 2 drives the internal magnet mechanism 1 to move, and then drives the driving device a to move, thereby driving the fluid.

[0228] The driving device a is driven by the power input driving device a to realize the extrusion and driving of the fluid.

[0229] The power input drive device a is provided with a rotating shaft for inputting power, which serves as a power input shaft.

[0230] The power input shaft is connected to an external driving device, and the power input shaft can be connected to the electric motor 8 or other driving devices.

[0231] Other driving devices may also be internal combustion engines, pneumatic motors and other driving devices.

[0232] The internal magnet mechanism 1 can be a single magnet, a permanent magnet or a soft magnet, or a combined structure, such as a permanent magnet wrapped in steel, a combination of several permanent magnets, or other combinations of permanent magnets and soft magnets.

[0233] The magnetic component in the external magnet mechanism 2 can be a soft magnet, a permanent magnet, an electromagnet, or a combination of more than one of them.

[0234] The front and rear in this patent are based on the movement direction of the driving device a.

[0235] For example, the front of the fluid inlet 5 is the direction in which the internal magnet mechanism 1 continues to move forward after passing through (or passing by) the fluid inlet 5 .

[0236] For example, the rear of the fluid inlet 5 is the opposite direction in which the internal magnet mechanism 1 continues to move after passing (passing) the fluid inlet 5. Therefore, the direction is established based on the closer relationship, and the valve 4 is behind the fluid inlet 5.

[0237] The power input drive device a includes a power linkage mechanism 81, which can be a rotating mechanism. The power linkage mechanism 81 is provided with a magnet mechanism that is linked to the internal magnet mechanism 1 through magnetic force, called the external magnet mechanism 2.

[0238] The power input drive device a for driving the rotor to rotate may be provided with a speed change system a2 for reducing the output speed.

[0239] So that when the rotor of the electric motor 8 rotates more times, the external magnet mechanism 2 rotates fewer times, thereby improving power output.

[0240] The speed change system a2 allows the rotation speed of the external magnet mechanism 2 and the internal magnet mechanism 1 to be reduced, thereby reducing centrifugal force, friction, and the number of times the valve 4 is opened and closed, thereby increasing the service life of the equipment and improving thrust and conversion efficiency.

[0241] More preferably, the power input drive device a driving the rotor is a speed change system a2 with a speed ratio greater than 30. When the rotor of the motor 8 rotates more than 30 times, the power input drive device a drives the external magnet mechanism 2 to rotate once.

[0242] Ensure that the internal magnet mechanism 1 can generate a large thrust when the rotation speed is not high.

[0243] More preferably, the power input drive device a for driving the rotor to rotate can adopt a transmission system a2 with a speed ratio greater than 50 and less than 300. The power input drive device a drives the rotor of the motor 8 to rotate 50 to 300 times, and the external magnet mechanism 2 rotates one time.

[0244] Under the premise of ensuring that the rotation speed of the internal magnet mechanism 1 is not high and the rotation resistance is not too large, good output thrust is achieved. In addition, by controlling the speed ratio, the complexity of the speed change system a2 is reduced and the reliability is improved.

[0245] The external magnetic mechanism 2 that is magnetically linked to the internal magnetic mechanism 1 can achieve magnetic linkage through mutual attraction or repulsion.

[0246] The inner wall of the circulation pipe 3 can be a circular tubular structure with a perfect circular or elliptical cross section, or a polygonal tubular structure with a triangular or quadrilateral cross section. In the case of a polygonal tubular structure, it is preferred that the corners of each side be connected in an arc shape.

[0247] The circulation pipe 3 allows access to the valve 4 structure through a connection section outside of the circulation pipe 3. This allows for independent production of the valve 4 structure. This facilitates modularization, reducing production complexity. This results in a simpler structure and easier maintenance and repair.

[0248] Because there are no high-speed rotating or precisely meshing components such as piston compressors, screw compressors, turbo compressors, scroll compressors, fans, and pumps, impure fluids containing impurities can enter. Compared with traditional fluid electric systems, the requirements for fluid composition are greatly reduced. The requirements for fluid quality are far lower than those of traditional equipment.

[0249] This also allows for increasing the area of ​​the fluid inlet 5, thereby reducing the fluid velocity while maintaining high flow, avoiding shock and maintaining high power. Furthermore, because the flow rate is increased by enlarging the fluid inlet 5, reducing the fluid velocity does not consume additional mechanical energy, ensuring efficiency.

[0250] Because in this patent, a circulation pipe 3 is provided, which allows the circulation pipe 3 to be relatively long, the fluid can be accumulated more in the circulation pipe 3, so it has a strong buffering capacity for high-pressure fluid and a strong accumulation capacity for low-pressure fluid.

[0251] In other words, the technical solution in this patent can operate well in high-pressure fluid environments as well as low-pressure fluid environments. It can operate well in environments with large fluid volumes as well as small fluid volumes. Its adaptability to pressure environments and flow rates is far greater than that of traditional equipment.

[0252] Furthermore, since the circulation pipe 3 in this patent can be designed to be much larger than the working space of traditional equipment at a relatively low cost, the fluid in the circulation pipe 3 can be squeezed for a long time and at a large stroke, which is convenient for heat release and improves efficiency.

[0253] A lubricating oil supply system is also provided, which includes an oil storage device connected to an oil supply pipeline, which is connected to an oiling component 7 for applying lubricating oil;

[0254] The oiling component 7 is connected to the channel of the circulation pipe 3.

[0255] When the drive device a passes through the oiling component 7, the drive device a is oiled to reduce friction. Because the oiling component 7 is arranged in the channel, oiling can be carried out during work without the need to stop the machine.

[0256] When the driving device a passes through the oil coating member 7, the internal magnet mechanism 1 is oiled, forming an oil seal.

[0257] The fluid loss through the side a of the driving device is reduced, and the energy utilization efficiency is higher.

[0258] The oiling member 7 is preferably provided between the fluid outlet 6 and the valve 4 .

[0259] The oiling component 7 is prevented from being subjected to high-pressure or high-speed fluid, the lubricating oil is prevented from being pushed back, and the lubricating oil is prevented from being blown into the fluid, thereby ensuring the oiling effect and avoiding lubricating oil waste.

[0260] It is further preferably arranged above the fluid outlet 6 and the valve 4. Gravity can be used to make the lubricating oil slide down automatically without the need for smearing in all directions.

[0261] Alternatively, the lubricating oil supply system may be provided with an electric control system for controlling whether to apply oil.

[0262] Specific implementation of the collocation setting of the internal magnet mechanism and the external magnet mechanism:

[0263] The external magnet mechanism 2 attracts the internal magnet mechanism 1 in the circulation pipe 3 from at least one side through magnetic force;

[0264] The power linkage mechanism 81 limits the rotation trajectory of the external magnet mechanism 2 to , allowing it to coincide with the rotation trajectory of the internal magnet mechanism 1 .

[0265] The power linkage mechanism 81 may include a rotatable connecting rod or a rotating disk.

[0266] For example, if the circulation pipe 3 is in the shape of a circular ring, the power linkage mechanism 81 limits the rotation trajectory of the external magnet mechanism 2 to a matching circular ring shape.

[0267] Furthermore, the power linkage mechanism 81 is connected to the external magnet mechanism 2 via a retractable member 82 that is retractable in the direction of the rotation radius. This allows the rotation trajectory of the external magnet mechanism 2 to be not limited to a standard circular shape, but can be an ellipse or even other shapes.

[0268] This design can reduce the requirements on the shape of the circulation conduit 3. In this way, the circulation conduit 3 is allowed to adopt an ellipse or even other forms of shape.

[0269] Furthermore, a movable component with an axial movable range is provided between the power linkage mechanism 81 and the external magnet mechanism 2 .

[0270] This allows the rotation trajectory of the external magnet mechanism 2 to transcend the plane, further reduces the requirements on the shape of the circulation pipe 3, and allows the circulation pipe 3 to be constructed in a three-dimensional shape.

[0271] Furthermore, the power linkage mechanism 81 is connected to the external magnet mechanism 2 via a retractable member 82 that is retractable in the direction of the rotation radius. Furthermore, a movable member with an axial range of motion is provided between the power linkage mechanism 81 and the external magnet mechanism 2. This allows the circulation duct 3 to be constructed into a complex three-dimensional shape.

[0272] Specific implementation of the combination of the internal magnet mechanism and the external magnet mechanism 2:

[0273] It should be noted that experiments have shown that during the startup process, when the internal magnet mechanism 1 has not completed magnetic linkage with the external magnet mechanism 2, a higher speed is likely to be generated because the external magnet mechanism 2 has no load.

[0274] If the magnetic force between the internal magnet mechanism 1 and the external magnet mechanism 2 has just completed the magnetic linkage, the external magnet mechanism 2 will quickly rush over the position of the internal magnet mechanism 1, only causing the internal magnet mechanism 1 to shake or vibrate, and the magnetic linkage drive cannot be completed.

[0275] This patent is set as:

[0276] The magnetic force of the linkage between the internal magnet mechanism 1 and the external magnet mechanism 2 is more than 5 times greater than the pulling force required for the internal magnet mechanism 1 to drive the external magnet mechanism 2 and maintain synchronous operation.

[0277] In order to enhance the magnetic force, the following designs can be adopted.

[0278] The internal magnet mechanism 1 includes at least one sheet-shaped permanent magnet magnetized in the thickness direction; the external magnet mechanism 2 includes at least one other sheet-shaped permanent magnet magnetized in the thickness direction; the two permanent magnets are linked by magnetic force.

[0279] Setting it in sheet shape can achieve a larger magnetic action area under the premise of smaller volume and lower cost, thus forming a more stable magnetic linkage.

[0280] The inner side of the circulation pipe 3 (the side close to the center of the arc) is at least partially formed into a tube surface structure, and the sheet-shaped permanent magnets of the internal magnet mechanism 1 are close to the inner side of the tube surface;

[0281] The tube surface is at least a cross-sectional structure of a tube wall in the shape of a circular tube, and is a surface structure in which a plane is bent into an arc shape.

[0282] The tube surface can be a complete cylindrical shape on the inside or an incomplete ring shape, but it is not a circular cross-section.

[0283] Setting at least the inner side of the circulation pipe 3 as a pipe surface facilitates the inner side to be formed by bending a flat metal plate or plastic plate or other plate-like material into an arc shape, which has the advantages of simple production process, low cost and reliable performance.

[0284] At least one of the internal magnet mechanism 1 and the external magnet mechanism 2 uses a strip-shaped sheet permanent magnet, or a sheet permanent magnet with a slightly curved surface, which also has the characteristics of simple production process and low cost.

[0285] At least one of the internal magnet mechanism 1 and the external magnet mechanism 2 is provided with a rolling mechanism, the rolling surface of the rolling mechanism directly or indirectly presses against the wall of the circulation pipe 3, and the permanent magnet is supported to leave the wall of the circulation pipe 3 through the rolling mechanism.

[0286] The rolling mechanism may be arranged on a permanent magnet.

[0287] The rolling mechanism may also be arranged on a bracket, and the permanent magnet is mounted on the bracket.

[0288] The pressure and friction generated by the permanent magnet on the wall of the circulation pipe 3 due to magnetic force are reduced.

[0289] Following is another structure.

[0290] It can be configured that the external magnet mechanism 2 includes at least two permanent magnets, and the at least two permanent magnets are arranged on at least two sides of the circulation pipe 3;

[0291] The magnetic directions of at least two permanent magnets are the same and converge to the conducting direction of the channel inside the circulation pipe 3 .

[0292] The internal magnet mechanism 1 has a magnetic direction of , and the two permanent magnets on the two sides of the external magnet mechanism 2 attract each other.

[0293] They can also be mutually exclusive.

[0294] This reduces or even eliminates the pressure exerted by the internal magnet mechanism 1 on the inner wall of the circulation pipe 3, thereby reducing resistance and friction, improving work efficiency and reducing equipment loss.

[0295] In the above design, the magnetic directions of the at least two permanent magnets are aligned with the conduction direction, that is, aligned with the movement direction of the internal magnet mechanism 1. The at least two permanent magnets are arranged on at least two sides of the circulation pipe 3, that is, they are not parallel on a plane, but are arranged in a three-dimensional space.

[0296] This allows the magnetic field strength of at least two permanent magnets to be achieved in the front-to-back direction, extending the magnetic field further than a single permanent magnet. Experiments have shown that even if the volume of a single bar-shaped permanent magnet is large enough, equal to the combined volume of at least two permanent magnets, it still cannot achieve the magnetic field extension achieved by the above structure.

[0297] In the above design, the internal magnet mechanism 1 can be subjected to a magnetic field induction force at a farther distance, or be subjected to a stronger magnetic field induction force at the same distance.

[0298] The external magnet mechanism 2 includes at least two permanent magnets and a bracket, and the at least two permanent magnets are fixed on the bracket;

[0299] In the front-to-back direction, at least two permanent magnets have an overlapping area of ​​at least one-half of their length.

[0300] Avoid at least two permanent magnets being too far apart to weaken the superposition effect of the magnetic fields.

[0301] Alternatively, two permanent magnets arranged opposite to each other may be fixed on the bracket, and the circulation pipe 3 is located between the two permanent magnets.

[0302] It can be that two permanent magnets are fixed on the bracket, and the centers of the two permanent magnets are respectively perpendicular to the central axis of the circulation pipe 3, and the angle formed by the two perpendicular lines is greater than 46 degrees and less than 120 degrees.

[0303] Preferably, two permanent magnets are fixed to the bracket, and the angle between the two planes where the two permanent magnets are located is greater than 80 degrees and less than 110 degrees, forming a nearly vertical structure. This facilitates magnetic field arrangement and allows each permanent magnet to be closer to the internal magnet mechanism 1.

[0304] Referring to FIG4 , it is further preferred that two permanent magnets 21 are fixed to the bracket 22 in an opposed arrangement, with the circulation pipe 3 located between the two permanent magnets 21. A magnet is also provided between the two permanent magnets, positioned on the side thereof. At least three permanent magnets 21 surround the circulation pipe 3 on three sides.

[0305] On the bracket, a permanent magnet can be arranged on one side of the fourth surface of the circulation pipe 3, and an opening can be left on the fourth surface.

[0306] The opening is left so that the external magnet mechanism 2 can slide off from the circulation pipe 3 or avoid the fluid inlet 5 and the fluid outlet 6.

[0307] Furthermore, the internal magnet mechanism 1 can be configured such that the magnetic direction is in the front-to-back direction, with the south pole in front and the north pole in the back, or vice versa.

[0308] Whether the internal magnetic mechanism 1 and the external magnetic mechanism 2 are approaching or moving away from each other, the attractive force and the repulsive force can be more scalable, thereby generating a longer-lasting or stronger force.

[0309] Furthermore, the internal magnet mechanism 1 can be arranged behind the external magnet mechanism 2 and arranged as a magnetic arrangement structure that generates a repulsive force;

[0310] When the internal magnet mechanism 1 moves forward, it pushes the external magnet mechanism 2 forward through the repulsive magnetic force.

[0311] By pushing with repulsive magnetic force instead of attracting, the pressure exerted by the internal magnetic mechanism 1 on the channel inside the circulation pipe 3 can be weakened, thereby effectively reducing friction.

[0312] In order to facilitate production, the external magnet mechanism 2 can integrate the three-dimensional structure including at least two permanent magnets into an integral three-dimensional permanent magnet structure.

[0313] The permanent magnet of the external magnet mechanism 2 may have a curved surface structure that fits the outer wall of the circulation pipe 3, so as to form a closer magnetic connection with the internal magnet mechanism 1 in the circulation pipe 3 and generate a stronger magnetic force.

[0314] For example, a circulation pipe 3 with an inner wall of a circular tube structure is used, and the internal magnet mechanism 1 uses a permanent magnet or soft magnet whose outer edge fits the shape of the inner wall of the circulation pipe 3; while the external magnet mechanism 2 uses a concave, arc-shaped structure that fits the outer wall of the circulation pipe 3.

[0315] Moreover, the external magnet mechanism 2 does not adopt a structure that completely surrounds the circulation pipe 3 , and the structure of the external magnet mechanism 2 is set to avoid the fluid inlet 5 .

[0316] Furthermore, during the rotation of the external magnet mechanism 2 , there will be no rotation obstruction caused by the pipeline at the fluid inlet 5 .

[0317] It can also be arranged that the external magnet mechanism 2 adopts a structure that completely surrounds the circulation pipe 3, but an openable opening part is provided at a position where it passes through the fluid inlet 5.

[0318] The openable opening member may be, for example, an elastic opening mechanism. When squeezed by the pipeline at the fluid inlet 5 , the elastic opening mechanism opens, thereby allowing the external magnet mechanism 2 to pass through the pipeline at the fluid inlet 5 .

[0319] At least two internal magnet mechanisms 1 are provided in the circulation pipe 3, and the two internal magnet mechanisms 1 are two repelling permanent magnet mechanisms;

[0320] The power linkage mechanism 81 is provided with at least two external magnet mechanisms 2 , and the two external magnet mechanisms 2 are respectively connected to two repelling permanent magnet mechanisms through magnetic force.

[0321] By providing at least two repelling permanent magnet mechanisms, a distance between the at least two repelling permanent magnet mechanisms is maintained within the circulation pipe 3. Furthermore, the at least two external magnet mechanisms 2 are magnetically connected to the at least two repelling permanent magnet mechanisms, which also maintains a distance between the at least two external magnet mechanisms 2, thereby achieving a relatively balanced power input and allowing for a stronger power input.

[0322] Furthermore, the two external magnet mechanisms 2 are both soft magnets, and are respectively attracted and connected to the two repelling permanent magnet mechanisms.

[0323] After the internal magnetic mechanism 1 and the external magnetic mechanism 2 are separated due to excessive force, the external magnetic mechanism 2 is made of soft magnets and can be magnetically connected again more easily and quickly.

[0324] It also includes a circulation pipe support system 31 that plays a supporting role. A fixing mechanism 32 is provided on the side of the circulation pipe 3, and the circulation pipe 3 is fixed to the circulation pipe support system 31 through the fixing mechanism 32;

[0325] The fixing mechanism 32 does not hinder the movement of the external magnet mechanism 2 .

[0326] The circulation pipe support system 31 can be a base or the shell of the entire equipment.

[0327] By suspending the circulation pipe 3 through the fixing mechanism, the external magnet mechanism 2 can have a larger installation space.

[0328] Furthermore, the fixing mechanism has a thickness less than 1.2 times the thickness of the circulation pipe 3 within a distance less than 0.5 cm from the circulation pipe 3 .

[0329] In this way, the external magnet mechanism 2 can be allowed to protrude by at least 0.5 cm when it is sleeved or plugged into the circulation pipe 3, and the permanent magnet can be provided on a length of at least 0.5 cm.

[0330] This at least 0.5 cm length space is particularly critical for the magnetic force of the internal magnet mechanism 1 in the circulation pipe 3 after the permanent magnet is installed, and can further optimize the force balance of the internal magnet mechanism 1.

[0331] Because the design of this patent needs to avoid the fluid inlet 5 and the fluid outlet 6, it is not convenient for the external magnet mechanism 2 to be completely closed into a ring. Therefore, the magnetic field at the opening of the external magnet mechanism 2 is weak, which will cause uneven force on the internal magnet mechanism 1 in the circulation pipe 3.

[0332] By adding a permanent magnet that extends out at least 0.5 cm, the magnetic field at the opening can be effectively compensated, so that the force on the internal magnet mechanism 1 in the circulation pipe 3 is relatively uniform again. This has a positive technical effect on avoiding vibration during movement and reducing friction.

[0333] Going a step further:

[0334] One of the magnetic poles of the internal magnet mechanism 1 is close to the inner wall of one side of the circulation pipe 3, and the other magnetic pole is close to the inner wall of the opposite side of the circulation pipe 3;

[0335] The two magnetic poles of the internal magnet mechanism 1 are connected by a magnetic conductive material;

[0336] One of the magnetic poles of the external magnet mechanism 2 is close to the outer wall of one side of the circulation pipe 3, and the other magnetic pole is close to the outer wall of the opposite side of the circulation pipe 3;

[0337] The two magnetic poles of the external magnet mechanism 2 are connected by a magnetic conductive material;

[0338] The two magnetic poles of the inner magnet mechanism 1 attract the two magnetic poles of the outer magnet mechanism 2 that are adjacent to each other.

[0339] In this way, the magnetic field loops of the internal magnetic mechanism 1 and the external magnetic mechanism 2 can form a closed shared magnetic field loop. This not only generates a stronger linked magnetic force, but also effectively locks the magnetic field, reducing its external influence and the attraction to external ferrous components and iron-containing dust.

[0340] Specific implementation of the combination of the internal magnet mechanism and the external magnet mechanism three:

[0341] 2 , the magnet in the internal magnet mechanism 1 is a sliding magnet, and is provided with at least one metal ring 11 with an elastic force that expands outwards; the metal ring 11 reduces the gap between the magnet and the inner wall of the circulation pipe 3 .

[0342] Furthermore, a groove is provided on the magnet in the internal magnet mechanism 1 , the metal ring 11 is embedded in the groove, and the outer edge protrudes from the groove, and the metal ring 11 is provided with an opening.

[0343] The space conditions are improved by elastically pressing and expanding the opening.

[0344] The axial direction of the metal ring 11 is consistent with the forward direction of the magnet and can be tilted appropriately to improve the airtight effect.

[0345] The magnet may be a cylindrical magnet.

[0346] Preferably, the curvature of the magnet is in the shape of a strip and fits the inner wall of the circulation pipe 3. This reduces the turning resistance and improves the airtightness.

[0347] Furthermore, at least two grooves are provided on the magnet in the internal magnet mechanism 1, and at least two metal rings 11 with openings are respectively embedded in the at least two grooves, and the outer edges protrude from the grooves; and the openings of the two adjacent metal rings 11 are staggered, and the staggered angle is not less than 10 degrees.

[0348] In order to make the metal ring 11 have the elasticity of expansion, an opening is provided, but the opening is not airtight. In order to solve the problem of airtightness, a plurality of metal rings 11 are used, and the opening angles are staggered.

[0349] When the fluid flows through the at least two staggered openings, flow resistance is generated, thereby improving air tightness.

[0350] The external magnet mechanism 2 includes two magnetic components, which are respectively located on two sides outside the circulation pipe 3 and generate attractive or repulsive magnetic forces with the north and south poles of the permanent magnet.

[0351] The two magnetic components of the external magnet mechanism 2 are connected via a magnetic conductive component.

[0352] In this way, more magnetic fields of the permanent magnets in the internal magnet mechanism 1 can pass through the two magnetic components and be connected through the magnetic conductive component, thereby generating a greater magnetic force on the two magnetic components.

[0353] Furthermore, the two magnetic components and the magnetic conductive component adopt an integrated structure. That is, the two magnetic components and the magnetic conductive component are an integrated magnetic component. It can be a soft magnetic component or a permanent magnetic component.

[0354] In this patent, preferably, the two magnetic components and the magnetic conductive component adopt an integrated permanent magnetic structure.

[0355] For example, the external magnet mechanism 2 may be a permanent magnet with both ends bent upward.

[0356] To achieve a stronger magnetic field force.

[0357] Furthermore, the external magnet mechanism 2 is not in contact with the circulation pipe 3 .

[0358] To avoid contact friction, frictional force and equipment wear, this can be achieved by arranging the running track of the power linkage mechanism 81.

[0359] Furthermore, the external magnet mechanism 2 is connected to the outside of the circulation pipe 3 via a rolling component.

[0360] For example, the external magnet mechanism 2 is connected to the outside of the circulation pipe 3 through a rolling system.

[0361] For example, at least one rolling component such as a ball or a roller can be installed in the external magnet mechanism 2 , and a track for the rolling component to roll can be provided outside the circulation pipe 3 .

[0362] This allows the two to be relatively fixed, and rolling friction can be used to reduce friction and wear.

[0363] Specific embodiment 1 of valve control:

[0364] 6 , the valve 4 may be a valve 4 that restricts the flow from the outlet direction to the fluid inlet 5 direction.

[0365] The valve 4 can also be a mechanically linked valve 4, where a mechanical switch 41 is provided on the running track of the driving device a, and the mechanical switch 41 is linked to the valve 4; when the mechanical switch 41 is triggered during the operation of the driving device a, the valve 4 opens.

[0366] The mechanical switch 41 can be arranged between the fluid outlet 6 and the valve 4 so as to open the valve 4 when the driving device a is close enough to the valve 4, thus avoiding the reverse flow of the fluid and wasting energy.

[0367] The distance between the mechanical switch 41 and the valve 4 is no greater than the length of the internal magnetic mechanism 1. This ensures that when the end of the internal magnetic mechanism 1 leaves the mechanical switch 41, the front end is already below the valve 4, supporting the valve 4 and preventing it from resetting before the internal magnetic mechanism 1 passes through. In particular, it prevents it from slipping.

[0368] The mechanical switch 41 is arranged at the upper part of the circulation pipe 3, and the valve 4 is a valve 4 that slides up and down.

[0369] This design facilitates the resetting of the mechanical switch 41 and the valve 4 by gravity, thereby improving operational reliability and reducing component count.

[0370] In addition, because the mechanical switch 41 is arranged at the top, the shaking generated when the internal magnet mechanism 1 passes through can be effectively avoided.

[0371] Furthermore, in front of the valve 4, another mechanical switch 41 is provided, and the other mechanical switch 41 is linked to the valve 4;

[0372] During the operation of the driving device a, after passing through the valve 4, another mechanical switch 41 is triggered, and the valve 4 is closed, pushing the fluid in the fluid inlet 5 to flow through the valve 4 to the fluid outlet 6.

[0373] Specific embodiment 2 of valve control:

[0374] It may also include an electronically controlled valve system; the electronically controlled valve system includes a sensor for sensing the position of the drive device a and a control circuit, and valve 4 is an electronically controlled valve;

[0375] The sensor is connected to the control circuit for communication, and the control circuit is connected to the electronically controlled valve;

[0376] The sensor is a sensor for generating a signal that enables the control circuit to control the electric control valve to open, and is called a valve 4 opening sensor.

[0377] When the driving device a reaches the specified position, the valve 4 is triggered to open the sensor and output a signal. After receiving the signal, the control circuit opens the electronically controlled valve.

[0378] The valve 4 opening sensor is arranged behind the fluid outlet 6 and is located at a position no more than one tenth of the length of the circulation pipe 3 away from the fluid outlet 6 .

[0379] Before the drive unit a reaches the fluid outlet 6, a sensor signal is generated, but premature opening of the electronically controlled valve is avoided, thus preventing waste of fluid energy. Simultaneously, a sensing signal to open the valve 4 is issued before the fluid reaches the fluid outlet 6, allowing the system to prepare in advance and effectively avoiding collisions caused by late opening of the valve 4.

[0380] This design is suitable for the case where the driving device a runs at a relatively high speed in the circulation pipe 3.

[0381] When the driving device a runs at a relatively slow speed in the circulation pipe 3 , or an electrically controlled valve with higher reliability and opening speed is used, the valve 4 opening sensor can be arranged in front of the fluid outlet 6 .

[0382] After passing through (passing or crossing) the fluid outlet 6, the valve 4 is opened again.

[0383] Specifically, it may be provided at a position between the fluid outlet 6 and the electrically controlled valve.

[0384] After the driving device a passes through the sensing area of ​​the valve opening sensor 4, the control circuit automatically delays a time period allowing the driving device a to pass through the electric control valve, and then automatically closes the electric control valve.

[0385] The time for the control circuit to delay itself can be a time period set manually, or a time period determined by parameters such as the operating speed of the internal magnet mechanism 1 and the fluid speed.

[0386] Alternatively, another sensor may be provided, located on the fluid inlet 5 side of the valve 4, and is a sensor for generating a signal for causing the control circuit to control the electric-controlled valve to close, and is called the valve 4 closing sensor.

[0387] The valve 4 closing sensor is arranged in front of the fluid inlet 5 and is located at a position no more than one tenth of the length of the circulation pipe 3 from the fluid inlet 5 .

[0388] The driving device a closes the electric control valve after passing the fluid inlet 5, but avoids closing the electric control valve too late to avoid wasting fluid energy.

[0389] When the driving device a runs at a relatively high speed in the circulation pipe 3 , the valve 4 closing sensor can be arranged behind the fluid inlet 5 .

[0390] Specifically, it may be provided at a position between the fluid inlet 5 and the electric control valve.

[0391] The driving device a is allowed to pass the position of the fluid inlet 5 by itself under the action of greater inertia. In this process, because the valve 4 is closed earlier, the waste of fluid energy can be avoided.

[0392] The valve 4 opening sensor and the valve 4 closing sensor can be a magnetic field sensing sensor or an optical sensing sensor.

[0393] The use of these two sensors can avoid frequent movement and wear of mechanical parts, and has the advantages of high stability, easy installation, and avoidance of direct contact with the drive device a.

[0394] The magnetic field sensing sensor can be a Hall sensor or a reed switch.

[0395] The optical sensing sensor can be a through-beam optical sensor or a reflective optical sensor.

[0396] The electronically controlled valve in the electronically controlled valve system is a valve 4 controlled by an electrical signal. It can be controlled by an electrical signal from a control circuit. The specific driving method is not limited and can be electric, pneumatic or other power.

[0397] The electrically controlled valve may be a pneumatic valve 4 controlled by an electrical signal.

[0398] Pneumatic valve 4 features high instantaneous power output and a fast response speed. This patented technical solution, under the influence of high-pressure fluid, requires a greater force to open valve 4 for a well-sealed structure. However, this faster response speed reduces the energy loss of the high-pressure fluid. Therefore, the use of pneumatic valve 4 offers the advantage of improved energy conversion efficiency under these operating conditions.

[0399] The electrically controlled valve may be a valve 4 driven by an electromagnet.

[0400] The electromagnet has the characteristics of instantaneous large power output and fast response speed.

[0401] This patented technical solution requires a relatively large force to open valve 4 under relatively high-pressure fluid, even for a relatively airtight structure. However, a faster response speed can reduce the energy damage of the high-pressure fluid. Therefore, the solenoid-driven valve 4, under these operating conditions, has the advantage of improving energy conversion efficiency, while also being simpler and more cost-effective.

[0402] The electrically controlled valve may also be a valve 4 driven by an electric motor (electric motor), which is suitable for a relatively general working environment.

[0403] Specific implementation of loop pipeline 1 (loop pipeline hierarchical structure):

[0404] The circulation pipe 3 is preferably made of an airtight, hard material.

[0405] The pipe wall of the circulation pipe 3 can be made of a single material structure or a combined material structure selected from metal, glass, ceramic, cement, sintered brick, glass fiber, plastic and the like.

[0406] The pipe wall is preferably made of glass.

[0407] The glass pipe wall has the advantages of easy installation of optical sensing sensors, strong impact resistance, easy observation of internal operating status, easy fault detection, and corrosion resistance.

[0408] Can be used in corrosive fluid environments.

[0409] The pipe wall is made of Teflon.

[0410] This kind of pipe wall has the advantages of being easy to form, easy to set up complex structures, low production cost, strong impact resistance, and strong corrosion resistance.

[0411] Particularly preferably, the pipe wall is made of at least one of stainless steel and aluminum alloy that is not attracted to the permanent magnet.

[0412] The pipe wall of the circulation pipe 3 can be a pipe wall of a composite structure, which includes a wall body and an airtight, smooth, hard attachment layer attached to the inner wall of the wall body.

[0413] When the volume of the circulation pipe 3 is relatively large, using a material with high airtightness, high smoothness and high hardness throughout the entire pipe will incur a large cost.

[0414] The above design utilizes an adhesive layer structure, allowing the wall to be constructed from lower-cost materials for support and protection, while the thinner adhesive layer can be constructed from more expensive materials with high airtightness, smoothness, and hardness. This ensures that the drive unit A operates in a low-friction, highly airtight environment while significantly reducing production costs.

[0415] The adhesion layer can be made of a pipe wall made of stainless steel, aluminum alloy, glass, aluminum oxide (Al2O3), or other materials with high air tightness, high smoothness, and high hardness.

[0416] The pipe wall of the large circulation pipe 3 is preferably a pipe wall of a composite structure.

[0417] Preferably, the pipe wall includes a wall body, which is made of at least one material selected from the group consisting of glass fiber, plastic, ceramic, cement, and sintered brick; and a silicon dioxide material layer is attached to the wall body.

[0418] Other chemical components can be added to silica to improve performance. The silica layer can be an enamel layer or a glass layer.

[0419] More preferably, the pipe wall includes a wall body, the wall body includes a matrix composed of at least one of ceramic, cement, and sintered brick, the inner side of the matrix is ​​paved with a plastic layer, and the inner side of the plastic layer is adhered with a glass layer.

[0420] The above-mentioned matrix is ​​easy to shape as a whole to provide structural support and shaping that is convenient for on-site construction. The plastic layer provides an aging-resistant and impact-resistant airtight layer, and the glass layer provides an impact-resistant and low-friction contact surface.

[0421] The substrate provides high-strength structural support at low cost and with minimal processing effort. The plastic layer, bonded to the substrate, facilitates shaping. Because the plastic layer acts as a buffer and seal, the glass layer can be made less airtight, allowing the glass layer to be assembled relatively simply by joining glass sheets together during the manufacturing process.

[0422] While ensuring performance, the production difficulty and cost are greatly reduced.

[0423] The plastic layer is preferably a Teflon layer, and the glass layer is preferably a glass layer spliced ​​together from tempered glass sheets.

[0424] This type of pipe wall using Teflon has the advantages of being easy to shape, easy to set up complex structures, low production cost, strong impact resistance, and strong corrosion resistance. In addition, the glass layer is a glass layer spliced ​​with tempered glass sheets, which is easier to adhere to the complex structure of the Teflon layer.

[0425] The above design not only solves the problem of large compression equipment being difficult to construct on site, but also reduces costs and ensures system performance.

[0426] The circulation pipe 3 may adopt a pipe wall of an integral structure or a pipe wall of a combined structure.

[0427] The circulation pipe 3 consists of two parts, one part is the lower pipe body located at the bottom, and the other part is the upper pipe body located at the top;

[0428] The upper tube body is buckled downwardly onto the lower tube body, surrounding and forming a tube cavity in the circulation tube 3 .

[0429] The split combined structure has the advantages of low manufacturing cost, easy installation, easy debugging and easy maintenance when manufacturing large electric systems.

[0430] During production, the pipe wall of the lower pipe body or the upper pipe body may be produced first, and then the material for forming the adhesion layer is coated on the pipe wall, and then the adhesion layer forming process is carried out.

[0431] For example, a glaze layer, a glass layer, or other layer-forming material is applied and then sintered to form a hard, adhered layer.

[0432] In this process, the use of a separate structure of the lower tube body and the upper tube body greatly improves the convenience for the coating and sintering work.

[0433] In actual production, the circulation pipe 3 can naturally be disassembled into two parts, left and right. However, this patent only adopts the method of disassembling the upper and lower parts. This method can effectively ensure the smoothness and firmness of the bottom layer, thereby improving the operating performance and compression efficiency.

[0434] Specific implementation of the circulation pipeline 2 (the pipeline shape and connection structure of the circulation pipeline):

[0435] The circulation pipe 3 allows access to the valve 4 structure through a connecting section outside of the circulation pipe. The annular pipe may not be closed by itself, but is closed by other auxiliary components, so that the driving device a can move in a circular manner.

[0436] Furthermore, it includes at least two layers of circulation pipes 3 arranged in parallel, and the at least two layers of circulation pipes 3 are respectively provided with a fluid inlet 5, a fluid outlet 6, a valve 4, and a driving device a.

[0437] The power input drive device a is provided with at least two external magnet mechanisms 2; the at least two external magnet mechanisms 2 and the at least two internal magnet mechanisms 1 are respectively linked by magnetic force.

[0438] The circulating fluid power system is provided with at least two circulating pipes 3;

[0439] At least two circulation pipes 3 are matched with at least two external magnet mechanisms 2 , and the at least two external magnet mechanisms 2 are driven by the rotor of the electric motor 8 .

[0440] The electric motor 8 drives at least two external magnet mechanisms 2 to provide power and realize common driving.

[0441] At least two external magnet mechanisms 2 may be arranged in parallel and connected to the same shaft, and then linked to the rotor of the motor 8 via the shaft to achieve common driving.

[0442] At least one external magnet mechanism 2 is connected to the rotating shaft via a one-way pushing mechanical mechanism.

[0443] The one-way pushing mechanical mechanism may be a ratchet mechanism, an overrunning clutch, or other one-way pushing mechanical mechanisms.

[0444] It is permissible that at least two external magnet mechanisms 2 are not synchronized, thereby enabling the system driven by the circulation pipes 3 of each layer to automatically coordinate the output energy.

[0445] It provides a technical basis for the system's stable operation and automatic balance of energy output.

[0446] At least two external magnet mechanisms 2 are respectively connected to the rotating shaft. The rotating shaft is divided into at least two sections. Two adjacent sections of the rotating shaft are connected by a coupling.

[0447] Therefore, the rotating shaft may not be a straight structure as a whole, but may be curved, and thus the circulation pipes 3 of each layer do not need to strictly adopt a stacked structure corresponding to each other, which is beneficial to optimizing the spatial layout.

[0448] The fluid outlets of at least two circulation pipes 3 are connected to a fluid container through interconnected pipes. The fluid container can be at least one of a pressurized gas container and a liquid container.

[0449] So that the pressure in at least two circulation pipes 3 can be automatically adjusted in a linked manner.

[0450] Specific implementation of the circulation pipeline three (the pipeline shape and connection structure of the circulation pipeline):

[0451] Referring to Figure 3, the serial circulation fluid power system includes a circulation fluid power system; the circulation fluid power system is provided with at least two circulation pipes 3; at least two circulation pipes 3 are respectively provided with a driving device a; at least two circulation pipes 3 are divided into an upper circulation pipe 3 and a secondary circulation pipe 3, and the fluid outlet 6 of the upper circulation pipe 3 is connected to the fluid inlet 5 of the secondary circulation pipe 3.

[0452] The circulation pipe 3 that the externally input fluid flows through first is called the upper circulation pipe 3, and the circulation pipe 3 that the externally input fluid flows through later is called the lower circulation pipe 3.

[0453] The designation may be relative, for example, a lower-level circulation pipe 3 of an upper-level circulation pipe 3 may be an upper-level circulation pipe 3 of a lower-level circulation pipe 3 of a lower level.

[0454] The fluid inlet 5 of the upper circulation pipe 3 is connected to the outside to input fluid;

[0455] After being driven by the driving device a and pressurized, it enters the secondary circulation pipe 3 and continues to be pressurized.

[0456] Since multiple circulation pipes 3 are connected in series, the fluid pressure at the fluid inlet 5 of the lower-level circulation pipe 3 can be increased, and then high-pressure fluid can be finally output while maintaining a small pressure difference between the fluid inlet 5 and the fluid outlet 6 of each lower-level circulation pipe 3.

[0457] This design allows the fluid to be pressurized multiple times and in stages through at least two circulation pipes 3 to generate more pressure.

[0458] The above design can avoid the impact of high pressure difference and protect the safety of the equipment, so that the equipment can operate well without installing other complicated pressure relief devices or strength-enhancing components.

[0459] It brings benefits in terms of energy conversion rate, safe and stable operation of equipment, and cost reduction.

[0460] For the system using external magnet mechanism 2, it can be optimized as follows:

[0461] At least two circulation pipes 3 are matched with at least two external magnet mechanisms 2. After the at least two external magnet mechanisms 2 are connected to the same rotating shaft, they are linked to the rotor of the motor 8 through the rotating shaft.

[0462] The electric motor 8 drives at least two external magnet mechanisms 2 to provide power and realize common driving.

[0463] The volume of the upper circulation pipe 3 at an angle value is greater than the volume of the upper circulation pipe 3.

[0464] In order to make the two driving devices a′ run at the same speed. In particular, when two external magnet mechanisms 2 are used, the two external magnet mechanisms 2 can move at the same speed and rotate at the same angle in the same time.

[0465] The secondary circulation pipe 3 can be provided with a smaller radius or a smaller cross-sectional area to obtain a smaller volume for pressurization. For example, the secondary circulation pipe 3 can be shorter or thinner.

[0466] 9 and 10 , the circulation pipe includes an annular groove and an annular upper cover;

[0467] The annular groove is covered with an annular upper cover to form an airtight annular channel.

[0468] Although it is simpler to form an annular channel by using seamless steel pipes and bent pipes, this patent adopts another solution.

[0469] The above design adopts a cover-closing method to form a channel, which has the advantage of being easier to process the internal structure than simply adopting a bent pipe structure.

[0470] It is easier to arrange the structure of the conductive mechanism.

[0471] An insulating layer is provided below the annular groove or on at least one of the outer and inner walls. The conductive mechanism comprises a strip conductor a6 fixed on the insulating layer.

[0472] Gravity and centrifugal force are used for pressing to make the contact stable.

[0473] The circulation pipeline is characterized by comprising an annular groove and an annular upper cover;

[0474] The annular groove is covered with an annular upper cover to form an airtight annular channel;

[0475] An insulating layer is provided below the annular groove or on at least one of the outer and inner walls. The conductive mechanism comprises a strip conductor a6 fixed on the insulating layer.

[0476] Gravity and centrifugal force are used for pressing to make the contact stable.

[0477] Furthermore: the circulation pipe 3 includes an inner ring and an outer ring having a height, an annular lower bottom having a width, and an annular upper cover;

[0478] The lower parts of the inner and outer rings are fixedly connected to the lower bottom of the ring;

[0479] The upper parts of the inner and outer rings are fixedly connected to the annular upper cover;

[0480] Then an airtight circulation pipe 3 is formed.

[0481] At least one of the annular lower base and the annular upper cover is fixedly connected to the inner ring and the outer ring by bolts inserted from the side;

[0482] A sealing strip is provided at the connection.

[0483] It not only realizes simple, stable and airtight connection, but also facilitates inspection and maintenance.

[0484] Fixing with bolts inserted from the side increases the difficulty of fixing and the cost of equipment, but avoids the risk of the bolts being subjected to expansion force and coming out in the axial direction.

[0485] The corners in the circulation pipe 3 adopt an inward-concave arc-shaped transition structure;

[0486] The driving device a is provided with a structure for shielding the fluid, which is called the fluid pushing mechanism a4;

[0487] The fluid pushing mechanism a4 is provided with a convex mechanism matching the concave one.

[0488] For example, while the inner surfaces of the inner ring and the lower base may be perpendicular, the connection is not a right-angled extension, but rather an extension of a concave (or inwardly concave) arcuate edge. This structure can form a more stable airtight structure with the fluid propulsion mechanism a4 during relative motion (without pursuing an absolute seal).

[0489] The arc-shaped transition structure can be formed by using an arc-shaped plastic strip with an inwardly concave outer cross-section. The plastic strip is laid and fixed along the corners in the circulation pipe 3 to form the arc-shaped transition structure.

[0490] The outer edge of the fluid pushing mechanism a4 is wrapped with a flexible sealing structure a5.

[0493] The device bracket is further provided with at least two rolling components supporting the fluid pushing mechanism a4, wherein the rolling components are at least one of balls, rollers, and rollers; the rolling components support the device bracket and the fluid pushing mechanism a4;

[0494] The electric system on the driving device a includes a motor a1, and the rotor of the motor a1 drives the rolling component to rotate;

[0495] The power input port of the electric motor a1 in the electric system is connected to at least two contacts.

[0496] At least two contacts are rolling contacts to reduce friction and avoid wear.

[0497] The rolling contact may be at least one of a roller, a ball, a roller, and a wheel with teeth.

[0498] The rolling component and the conductive roller are combined into one, so that the conductive roller has both conductive function and rolling support function.

[0499] A compressor using a circulating fluid power system is characterized in that it includes a compression device and a gas storage tank, and is characterized in that the compression device uses a circulating fluid power system.

[0500] It can be applied to air compressors, air conditioners and other equipment, which is beneficial to reducing energy consumption and increasing the output power of a single device.

[0502] It can be applied to industrial occasions where there are some debris. The debris is no longer easily broken by the fan fins, which can improve the air quality.

[0504] It can be used for propulsion of ships, submarines and other equipment.
